.ftpaccess files

The .ftpaccess file is used to give a measure of control to the
individual administrator of each VirtualHost without having to disturb
the sysadmin everytime a change is required. Each .ftpaccess file can
be considered to be a 'floating' section of the <Directory>
configuration block.

The file uses the same structure as the main daemon
configuration, though there are a significant number of directives
which have no meaning within the .ftpacess context.

There is no way to disable the use of .ftpaccess files, however
for servers with no shell access a simple file filter which blocks
.ftpaccess should suffice to prevent users from using the
functionality. There are also implications for letting untrained and
inexperienced end users from generating their own files as they may
lock themselves out of their space or leave it less secure than they
intend.
